Where does the turn take place in sonnet 30 by Shakespeare?

Sonnet 30 by Shakespeare does not have a specific "turn" or "volta" as it does not follow the traditional Petrarchan sonnet structure. The poem is a single stanza of 14 lines and does not have a clear shift in tone or idea that would constitute a turn. Instead, it maintains a consistent tone and theme throughout, expressing the poet's love and devotion for his beloved.
